Hereinafter, a detailed configuration of the server 1 for guiding and operating personal mobility 2 and cluster driving of the vehicle 3 will be described. Referring to FIG. 1 , the server 1 may include a first input device 110, a first display 120, a first controller 130, a first storage 131, and a first transceiver 140. In addition, to distinguish the components having the same name between the server 1, personal mobility 2, and vehicle 3, the ‘first’ is written in the component of the server 1, and the ‘second’ is written in the component of personal mobility 2 and the ‘third’ is written in the component of the vehicle 3.

In addition, information regarding the total driving time, the total driving distance, the remaining time, and the remaining distance may be displayed. Information of the personal mobility 2 and the vehicle 3 may include user information, identification information of the personal mobility 2, identification information of the vehicle 3.

The first display 120 may also be configured to display layout information for cluster driving. The first display 120 may also be configured to display a design mode when designing a layout for cluster driving. The first controller 130 may be configured to transmit a cluster driving proposal signal to another mobile body based on the current location information of at least one mobile body when a cluster driving request signal is received from at least one mobile body. In particular, the at least one mobile body may be at least one personal mobility or at least one vehicle.

When transmitting a cluster driving request signal, the first controller 130 may be configured to transmit information of a destination together. The first controller 130 may be configured to transmit a cluster driving proposal signal to another mobile body traveling within a certain distance based on the current location information of at least one mobile body. Additionally, the first controller 130 may be configured to transmit a cluster driving proposal signal to a mobile body capable of autonomous driving among other mobile bodies traveling within a certain distance based on current location information of at least one mobile body.

The first controller 130 may be configured to confirm another mobile body traveling within a certain distance based on the current location information of at least one mobile body, and transmit a cluster driving proposal signal to another mobile body having the same destination among the confirmed another mobile bodies. The first controller 130 may also be configured to determine whether the road of the current location is a road on which autonomous driving is capable of being performed based on current location information of the at least one mobile body and map information when a cluster driving request signal is received from at least one mobile body.

The first controller 130 may be configured to determine whether there is another mobile body that has approved cluster driving in response to transmission of the cluster driving proposal signal. The first controller 130 may be configured to determine whether cluster driving is possible on the road of the current location in response to whether at least one mobile body (e.g., a first mobile body) is personal mobility or vehicle, and in response to whether another mobile body (e.g., a second mobile body) that has approved cluster driving is vehicle or personal mobility.

For example, when at least one mobile body is a personal mobility, and another mobile body that has approved cluster driving is personal mobility, the first controller 130 may be configured to determine whether the road of the current location is a road through which personal mobility may travel, based on current location information and map information of at least one mobile body.

When at least one mobile body is vehicle, and another mobile body that has approved cluster driving is personal mobility, the first controller 130 may be configured to determine whether the road of the current location is a road through which both the personal mobility and the vehicle may travel, based on current location information and map information of at least one mobile body. When at least one mobile body is vehicle, and another mobile body that has approved cluster driving is vehicle, the first controller 130 may be configured to determine whether the road of the current location is a road through which the vehicle may travel, based on current location information and map information of at least one mobile body.

The first controller when both vehicle and personal mobility perform cluster driving will be described. The first controller 130 may be configured to confirm the road information in the route information based on the route information in the route from the current location (or origin) to the destination, guide and control cluster driving when the road in the route is a road where both the vehicle and personal mobility that requested and approved cluster driving may drive and a road on which autonomous driving is capable being performed based on the confirmed road information, and when both the vehicle and personal mobility that requested and approved cluster driving may perform the autonomous driving mode.

The first controller 130 may be configured to confirm the identification information of the vehicle and personal mobility that requested and approved cluster driving, respectively, obtain area size information for a safety area of the vehicle based on the confirmed identification information of the vehicle, and obtain area size information for a safety area of personal mobility based on the confirmed identification information of personal mobility.

As shown in FIG. 4 , the first controller 130 may be configured to obtain an area size information for a safety area A1 of a large-sized commercial vehicle 3 a, a safety area A2 of a medium-sized commercial vehicle 3 b, and a safety area A3 of a large-sized passenger vehicle 3 c, a safety area A4 of the medium-sized passenger vehicle 3 d and a safety area A5 of the small-sized passenger vehicle 3 e.

The first controller 130 may be configured to obtain a size of personal mobility and a braking distance of personal mobility based on identification information of personal mobility, and obtain area size information for a safety area of personal mobility based on the obtained size of personal mobility and the braking distance of personal mobility. The first controller 130 may be configured to obtain a size of vehicle and a braking distance of vehicle based on identification information of vehicle, and obtain area size information for a safety area of vehicle based on the obtained size of vehicle and the braking distance of vehicle. For example, the area size when the braking distance of personal mobility is short may be smaller than the area size when the braking distance of personal mobility is long. In addition, the area size when the vehicle braking distance is short may be smaller than the area size when the vehicle braking distance is long.

The first controller 130 may also be configured to obtain area size information corresponding to identification information of the vehicle from information stored in the first storage 131, and obtain area size information corresponding to identification information of personal mobility from information stored in the first storage 131. The first controller 130 may be configured to request to provide area size information for a safety area of a vehicle and personal mobility to perform cluster driving.

As shown in FIG. 5 , the first controller 130 may be configured to set the geo-fence area based on the area size information for the safety area of each vehicle to perform cluster driving and the area size information for the safety area of each personal mobility. The first controller 130 may be configured to determine the driving positions of vehicles to perform cluster driving in the set geo-fence area, and in response to determining the driving positions of vehicles, the first controller 130 may be configured to determine the driving positions of personal mobility, respectively, to design layout of the mobile bodies for cluster driving.

The first controller 130 may be configured to set a geo-fence area based on a size information of the plurality of vehicles and a size information of the plurality of personal mobility during cluster driving, determine driving positions of the plurality of vehicles as primary in the set geo-fence area based on the size information of the plurality of vehicles, determine driving positions of the plurality of personal mobility as secondary in the set geo-fence area based on the size information of the plurality of personal mobility and adjust layout information for the driving positions determined as the primary and the secondary to be transmitted to the plurality of vehicles and the plurality of personal mobility.

The design of the layout of mobile bodies for cluster driving will be described with reference to FIGS. 6A, 6B, and 6C. It will be described on the assumption that when the mobile body performing cluster driving is one large-sized commercial vehicle 3 a, two medium-sized commercial vehicles 3 b, three medium-sized passenger vehicles 3 d, three bikes 2 a, and two two-wheel kickboards 2 c.

As shown in FIG. 6A, when designing the layout of mobile bodies, the first controller 130 may be configured to place the vehicle 3 a having the first largest safety area A1 in the front area of the right lane among the lanes in the geo-fence area, and place the vehicle 3 b having the second largest safety area A2 in the front area of the left lane. The first controller 130, when another vehicle 3 b′ having the second largest safety area A2 is further present, may be configured to determine whether the other vehicle 3 b′ may be placed in a rear area of the right lane, determine whether it is possible to place in the rear area of the left lane in response to determining that placement in the rear area of the right lane is impossible and place another vehicle 3 b′ having the second largest safety area A2 in the rear area of the left lane in response to determining that placement is possible in the rear area of the left lane.

The first controller 130 may be configured to compare the size of the rear area of the right lane with the size of the safety area A2 and, in response to determining that the size of the rear area of the right lane is smaller than that of the safety area A2, may be configured to determine that the placement of another vehicle 3 b is impossible. The rear area of the right lane may be the area remaining after placing the vehicle 3 a (e.g., a first vehicle). In other words, the rear area of the right lane may be an area excluding the safety area A1 among the right lane areas of the geo-fence.

The first controller 130 may be configured to compare the size of the rear area of the left lane with the size of the safety area A2 and, in response to determining that the size of the rear area of the left lane is larger than that of the safety area A2, may be configured to determine that the placement of another vehicle 3 b (e.g., a second vehicle) is possible. The first controller 130 may be configured to compare the third largest safety area A4 with the remaining area of the right lane and the remaining area of the left lane among the geo-fence area, and determine whether a vehicle 3 d may be placed in the remaining area of the right lane or the remaining area of the left lane. In response to determining that the vehicle 3 d may be placed in the remaining area of the right lane, the first controller 130 may be configured to place the vehicle 3 d in the remaining area of the right lane. In response to determining that the vehicle 3 d is unable to be placed in the remaining area of the right lane, the first controller 130 may be configured to place the vehicle 3 d in the remaining area of the left lane.

As shown in FIG. 6B, in response to determining that the vehicle 3 d is unable to be placed in the remaining area of the right lane or the remaining area of the right lane, the first controller 130 may be configured to place the vehicle 3 d having the third largest safety area A4 in the front area of the central lane among the geo-fence areas. Here, the central lane may be one or two lanes.

The first controller 130, in response to determining that other vehicle 3 d′ (e.g., third vehicle) having the third largest safety area A4 is further present, may be configured to place other vehicle 3 d′ in some of the remaining areas of the central lane. The first controller 130, in response to determining that another vehicle 3 d′ having the third largest safety area A4 is further present, may be configured to place another vehicle 3 d′ in the remaining area of the central lane. The first controller 130 may be configured to obtain driving positions of all vehicles when all vehicles are placed in the geo-fence area.

As shown in FIG. 6C, the first controller 130 may be configured to obtain the remaining areas EA1 and EA2 after the vehicle is placed among the geo-fence areas and places three bikes 2 a and two two-wheel kickboards 2 c in the remaining areas. In particular, the remaining areas EA1 and EA2 after the vehicle is placed may be left and right areas between the vehicles. The first controller 130 may be configured to sequentially place personal mobility having a large safety area based on area size information of the safety area of the three bikes 2 a and two two-wheeled kickboards 2 c from the front area.

Considering the safety of vehicle and personal mobility, the first controller 130 may be configured to adjust the driving position of vehicles 2 d, 2 d′, 2 d″ placed in the central lane by a certain distance in the opposite direction in which personal mobility is placed. For example, when placing personal mobility in the remaining area EA1 on the right, the first controller 130 may be configured to move the driving position of the vehicle 2 d, 2 d′, 2 d″ placed in the central lane to the right by a certain distance. When placing personal mobility in the remaining area on the right EA2, the first controller 130 may be configured to move the driving position of vehicles 2 d, 2 d′, 2 d″ placed in the central lane to the left by a certain distance.

The first controller 130 may be configured to confirm the size of the remaining areas behind the left lane, behind the central lane, and behind the left lane among the geo-fence area after all vehicles are placed in the geo-fence area, and may also be configured to adjust the interval between the front and rear of vehicles placed in each lane based on the confirmed information on size. For example, the first controller 130 may be configured to adjust the interval between the vehicle 3 d′ and the vehicle 3 d″ placed in the central lane of the geo-fence area.

An example of designing the layout of mobile bodies based on the lane width and the number of lanes will be described with reference to FIGS. 7A and 7B. As shown in FIG. 7A, the first controller 130 may be configured to obtain lane width information of the road based on map information and current location information and place personal mobility in two rows between vehicles respectively placed in two adjacent lanes in response to determining that the lane width W of the road is equal to or greater than the reference width based on the obtained lane width information.

As shown in FIG. 7B, the first controller 130 may be configured to obtain lane width information of the road based on map information and current location information and place personal mobility in two or more rows in a rear area EA3 remaining after the vehicle is placed among the geo-fence areas in response to determining that the lane width W of the road is less than the reference width or the number of lanes is less than the reference number based on the obtained lane width information. As shown in FIG. 7B, in response to determining that the number of lanes is less than the reference number, the first controller 130 may be configured to confirm the lane in which a vehicle having a safety area (e.g., A4) less than a predetermined size is placed, and may also be configured to place personal mobility in and around the confirmed lane.

When the design mode selected during layout design is the size mode, the first controller 130 may be configured to design the layout based on the size of the vehicle and personal mobility performing cluster driving (see FIGS. 6A, 6B, 6C, 7A, 7B).
